"Public health promotes and protects the health of people and the communities where they live, learn, work and play."
"Public Health is the science and the art of preventing disease, prolonging life, and promoting physical health and efficiency through organized community efforts for the sanitation of the environment, the control of community infections, the education of the individual in principles of personal hygiene, the organization of medical and nursing services for the early diagnosis and preventive treatment of disease, and the development of the social machinery which will ensure to every individual in the community a standard of living adequate for the maintenance of health."

"Together, the [Surgeon General's] reports of the past four decades have expanded the very meaning of public health. They show that the definition of public health is not fixed but has changed over time, and changed the practice of medicine, as well, to include areas such as human behavior and mental health. That fact has broad implications for our understanding of health and risk, personal pleasure and social norms, science and moral standards, and individual freedoms and public policy."
— From the Public Health Functions Steering Committee, 1994.
